  <section>
    <h1>Welcome to the libIIO</h1>
    <p style="margin-bottom:0em;">Thanks for your interest in the libIIO, a
    C/C++ library that provides generic access to Industrial Input Output (IIO)
    devices. IIO started as a <a href=
    "https://www.kernel.org/doc/html/latest/driver-api/iio/index.html">Linux
    kernel subsystem</a> to support for devices that that included
    analog-to-digital convertors (ADCs) and/or digital-to-analog convertors
    (DACs). While the libIIO continues to provide an easy interface to the
    Linux kernel IIO subsystem, it has also expanded beyond that, and is now
    just as common to see this used inside an embedded system or hypervisor as
    it is on a host PC.</p>
    <p style="margin-bottom:0em;">It is portable: Using a single cross-platform
    API, it provides access to IIO devices on Linux, macOS, Windows, etc across
    local and remote (USB, Network, Serial) devices. The library is composed by
    one high-level API, and several backends:</p>
    <ul>
      <li>the <b><i>local</i></b> backend, which interfaces the Linux kernel
      through the sysfs virtual filesystem,</li>
      <li>the <b><i>remote</i></b> backend, which communicates to an
      <b><i>iiod</i></b> server through a network, usb or serial (<a href=
      "https://en.wikipedia.org/wiki/RS-232">wired</a>, <a href=
      "https://en.wikipedia.org/wiki/USB_communications_device_class">USB
      CDC</a>, or <a href=
      "https://en.wikipedia.org/wiki/List_of_Bluetooth_profiles#Serial_Port_Profile_(SPP)">
        Bluetooth SPP</a>) link. The <b><i>iiod</i></b> server can run on a:
        <ul>
          <li>Linux host (an <a href=
          "https://github.com/analogdevicesinc/libiio/tree/master/iiod">IIO
          daemon</a> is included part of libIIO), this would typically
          communicate to a libIIO client over the network or USB; or
          </li>
          <li>a deeply embedded, resource constrained system (like Arduino)
          managed separately as <a href=
          "https://github.com/analogdevicesinc/libtinyiiod">tiny-iiod</a>; this
          would typically communicate to a libIIO client over the network, or
          serial.
          </li>
        </ul>
      </li>
    </ul>
    <p>It is entirely user-mode: No special privilege or elevation is required
    for the application to communicate with a device. One of the most powerful
    things about libiio is its <a href=
    "https://en.wikipedia.org/wiki/Remote_procedure_call">Remote Procedure
    Call</a> style interface. Moving backends from USB to Networking to local
    embedded does not require any code changes. The users of the libIIO do not
    need to code any differently for the remote interaction, making it easy to
    move from remote (debug on PC over Ethernet) to local (deployed on embedded
    Linux).</p>
    <h3>What platforms are supported?</h3>
    <p>Any host running Linux, macOS, Windows, or OpenBSD/NetBSD, should be
    trivial to get libIIO running on. If you are interested in porting to other
    hosts that support either networking (socket interface), <a href=
    "https://libusb.info/">libusb</a> or serial, it should be very
    straightforward. <a href=
    "https://github.com/analogdevicesinc/libiio/pulls">Pull Requests</a> are
    always reviewed, and well written ones are normally accepted.</p>
    <p>The local backend and Linux daemon can run on any embedded Linux based
    system, from purpose built systems like <a href=
    "http://www.analog.com/plutosdr">PlutoSDR</a> or <a href=
    "http://www.analog.com/adalm2000">ADALM2000</a> to <a href=
    "https://www.raspberrypi.org/">Raspberry Pi</a> or <a href=
    "https://beagleboard.org/">BeagleBoard</a> to <a href=
    "https://www.nvidia.com/en-us/autonomous-machines/jetson-store/">Jetson</a>.
    <a href="https://github.com/analogdevicesinc/libtinyiiod">tiny-iiod</a>
    requires a modern C compiler and is known to work on a variety of non-Linux
    frameworks including <a href="https://www.mbed.com/">Mbed</a> and <a href=
    "https://www.freertos.org/">FreeRTOS</a>.</p>
    <h3>Sounds good! How do I get started?</h3>
    <p>If you are using Linux, chances are your distribution already includes
    libIIO, so you probably just need to reference the <b><kbd>iio.h</kbd></b>
    header in your source.</p>
    <p>For other platforms, you are encouraged to use one of our <a href=
    "https://github.com/analogdevicesinc/libiio/releases/latest">release
    builds</a>. If if you want to use the very latest, you have the option to
    use a nightly build or build from source. Please check the Downloads
    menu.</p>
    <p>If you prefer, you can also access the source directly from <a href=
    "https://github.com/analogdevicesinc/libiio">github</a>.</p>
    <p>Once you have secured your access to the library and its header, please
    check the libIIO API or the libIIO examples.</p>
    <h3>Where is (insert my favourite language) support?</h3>
    <p>The mainline library is built in C, can be used in C++, and has built in
    bindings for Python and C# (C-Sharp). <a href=
    "https://github.com/drom/node-iio">Node.js</a> and <a href=
    "https://github.com/fpagliughi/rust-industrial-io">Rust</a> are maintained
    outside the main repo. If you are interested in creating more language
    bindings, please <a href=
    "https://github.com/analogdevicesinc/libiio/issues">reach out</a> to the
    developers by posting an issue on github.</p>
  </section>
  <section>
    <h3>Help and Support</h3>
    <p>If you have any questions regarding the libIIO or are experiencing any
    problems following the documentation, or examples, feel free to ask us a
    question. Generic libIIO questions can be asked on <a href=
    "https://github.com/analogdevicesinc/libiio/issues">Github Issue
    tracker</a>. Since libIIO provides connectivity to the kernel&#39;s IIO
    framework - many times the problem is actually in the driver. In this case,
    contact your favourite kernel developer. If you are using an <a href=
    "http://wiki.analog.com/linux">Analog Devices&#39;</a> component, feel free
    to ask on their <a href=
    "https://ez.analog.com/linux-software-drivers/">Linux support</a>
    forums.</p>

            with IIO drivers to make them easier to use. The libIIO interface,
            although extremely flexible, can be cumbersome to use due to the
            amount of boilerplate code required. This Python module has custom
            interfaces classes for specific parts and development systems which
            can generally make them easier to understand and use.
